Kevin Ryan makes it clear that the fires should have had a negligible
effect on the WTC towers, as he made clear in his letter
to NIST.

In post
29, shaman_ argued that Mr. Ryan bases that belief on the belief that the
steel didn't reach temperatures over 250C and that that view is mistaken.

This is true. But as I argued in post
44, it's understandable that Ryan was misled in this regard. In post
45, shaman_ argued that Ryan was not misled, but that he chose to ignore
all the evidence that the fires reached higher temperatures. In post 47,
I ask:
"Do you have any evidence
to support your claim? To me it seems clear that he was informing himself from
Frank Gayle's interim NIST report that he had just received."
